Question

I’m trying out Meteor’s Leaderboard example and am running into a bug in trying to randomize the players’ scores.

页: 1 在模拟援引/扮演者/更新未定义的的效力时,例外

相关法典也这样做:

 click input.randomize_scores : function () {
  Players.find().forEach(function (player) {
    random_score = Math.floor(Math.random()*10)*5;
    Players.update(player, {$set: {score: random_score}})
  });
}

我的感觉是,我在这里做的事情令人sil笑.。我确实赞赏一位协调人。

更新(更新)的第一个论点是文件ID或全刚果甄选者。你通过完整的参与者文件。引证:

Players.update(player._id, {$set: {score: random_score}});

简言之,

Players.update({_id: player._id}, {$set: {score: random_score}});
